26650 Mod Stand

*File Updated 9/14/2014- Bottom flattened. Should be much more stable.

*Update: I attempted to print it and failed due to forgetting to do supports. It's easy to forget about the underside curves. Printing now with rafts and supports.
My first model I feel worth releasing. Will be accompanied by a scaled 18650/ 22mm version
3 x 31mm mod holes
3 x 30mm RDA holes with 510
I have not printed this yet and only real worry are the following 2 things:
1. Depth of holes ok?
2. 510 diame
